It took me a while but I finally completed this mod, which started out as a FW1A Pro. This is what I did:
FET+7+1 driver upgraded to T1616 with aux support
Orange, green and purple aux
Yinding 5050 3000k emitter (warm and rosy, CRI > 70)
3D printed spacer (white PETG)
Aspheric lens
I am getting around 76000cd at turn on, which is very similar to what the Bean Master got with a CULPM1 and a smooth reflector. But remember this Yinding is 3000k and rosy with a duv of -0.0075, and I think this makes it very impressive.
The main reason why I used an aspheric lens is because I needed aux, and suitable TIRs are just not throwy enough. I would also like to try to put those tiny RGB aux leds between the emitter and a reflector in the future. Enjoy the photos (sorry that most of them are in the wrong orientation, I uploaded them with my phone and I don't think they let me set the orientation)
